The mine-used distributed seismic instrument is a geophysical prospecting equipment suitable for the complex environment of mines. It adopts a distributed arrangement and can realize multi-channel synchronous data acquisition. Its core function is to invert geological structures, such as faults and fractures, by receiving vibration signals from underground rock masses, so as to provide data support for mine advanced detection, roof stability assessment and other work. The equipment must have the characteristics of anti-interference, explosion-proof, and resistance to temperature and humidity changes, so as to adapt to narrow underground spaces and harsh working conditions, and help ensure the safe production of mines.
